[texts]Kinetic Theory- Linear Response - David Tong
The goal of response theory is to �gure out how a system reacts to outside in�uences. These outside in�uences are things like applied electric and magnetic �elds, or applied pressure or an applied driving force due to some guy sticking a spoon into a quantum liquid and stirring. ...

[texts]Optical Physics and Quantum Electronics- Plane Wave Propagation in a Linear, Homogeneous, Anisotropic Dielectric Media (Crystal Optics) - R. Victor Jones
Our objective here is to formulate a general approach to the subject of wave propagation in anisotropic dielectrics which makes use of ideas familiar from other branches of mathematical physics -- viz. the �eigenvalue problem.�.18 For reasons that will soon become abundantly clear, treatments of �crystal optics� focus on the behavior of the dielectric displacement vector, r D (r r , _) rather than on the electric field vector.19 For non-magnetic dielectrics the components of the dielectr...

[texts]Kinetic Theory- Kinetic Theory - David Tong
The purpose of this section is to lay down the foundations of kinetic theory, starting from the Hamiltonian description of 10^23 particles, and ending with the Navier-Stokes equation of �uid dynamics. Our main tool in this task will be the Boltzmann equation.This will allow us to provide derivations of the transport properties that we sketched in the previous section, but without the more egregious inconsistencies that crept into our previous derivaion...

[texts]Mathematics for Computer Science - Relations and Partial Orders - Albert R. Meyer
A relation is a mathematical tool for describing associations between elements of sets. Relations are widely used in computer science, especially in databases and scheduling applications. A relation can be de�ned across many items in many sets, but in this text, we will focus on binary relations, which represent an association between two items in one or two sets.

[texts]Mathematical Methods 3 - Jonny Evans
This course is an introduction to some of the most ingenious ideas in 18th century mathematics. The course is divided into two parts. In the �rst part we will see how to turn some natural physical and geometric problems into di_erential equations. The second part of the course will develop techniques to solve some partial di_erential equations.

[texts]General Relativity (Notes for Px436) - Tom Marsh
These notes mostly show the essentials of the lectures, i.e. what I write on the board. The exception to the rule is when I write pieces of text like this (outside of the examples). These represent information that I may have said but not written during lectures. I use them when I think it would help you follow the notes. The notes are very terse, and brief to the point of grammatical inaccuracy.This is because they are notes and are not intended to replace books...

[texts]Colliding Plane Waves in General Relativity- Chapter 18 - Colliding Electromagnetic Waves- Diagonal Solutions - Jerry Griffiths
This chapter is a continuation of the review of all presently known exact solutions which describe the collision of plane electromagnetic waves, or a combination of both gravitational and electromagnetic waves. Attention is concentrated here only on diagonal solutions. These solutions may be considered as a generalization of the solutions representing the collision of gravitational waves with colinear aligned polarization that have been described in Chapter 10...

[texts]General Physics I- Thermal Physics 1 - Lawrence Evans;Mr. J. Edward Ladenburger
In the following sections we will treat macroscopic systems that are in thermal equilibrium. Most of our discussion will center on the behavior of gases. We will use appropriate macroscopic variables, some of which are already familiar, such as density, volume and pressure. We will usually assume the CM of the system is at rest, and that molecular velocities are randomly distributed as to direction, so there is no bulk �ow or velocity �eld to consider...

[texts]Thermal Energy- Part2C - Introduction to Thermochemistry - Zoltan Spakovszky
In this section, we examine the issue of how we obtain the heat needed for work production. For the most part, this is from converting chemical energy into heat, so the discussion will be on reacting mixtures of gas which are involved in chemical combustion processes. The topic addressed is �thermochemistry�, which is the combining of thermodynamics with chemistry to predict such items as how much heat is released from a chemical reaction...

[texts]General Physics II- Magnetostatics 1 - Mr. Travis Byington;Lawrence Evans;Mr. Ryan Magee;Hao Zhang
We begin our discussion with magnetic �elds that are static, i.e., independent of time. The �eld is de�ned by its effect on a moving point charge. Then we discuss steady currents as sources of magnetic �elds, exploring some useful and important special con�gurations of currents. Later on we will discuss another important source of magnetic �elds, an electric �eld that is changing with time.

[texts]Colliding Plane Waves in General Relativity- Chapter 12 - Solution-Generating Techniques - Jerry Griffiths
In this chapter we will consider only vacuum solutions. This will enable us to continue to concentrate on the collision of gravitational waves. Various techniques will be discussed here, and the main solutions that have been obtained using them will be described in the next chapter. Many techniques are also known by which solutions of the Einstein�Maxwell equations, and other non-vacuum solutions, can be generated from known vacuum solutions...

[texts]Colliding Plane Waves in General Relativity- Chapter 6 - The Field Equations - Jerry Griffiths
The colliding wave problem has been described in terms of two approaching waves in regions II and III, in a background region I, which is here taken to be �at. According to the work of Penrose (1980), the initial data are well set, so that a unique solution exists in the interaction region IV at least in the neighbourhood of the boundaries of regions II and III. It is therefore necessary �rst to state the relevant �eld equations in the interaction region, and then to attempt to solve them ...

[texts]Colliding Plane Waves in General Relativity- - Introduction - Jerry Griffiths
The subject to be discussed in this book is the collision and interaction of gravitational and electromagnetic waves. This is a particularly importanttopic in general relativity since the theory predicts that there will be a non-linear interaction between such waves. The e_ect of the non-linearity, however, is unclear. It is appropriate therefore to look in some detail at the simplest possible situation in which the e_ect of the non-linearity will be manifest: namely the interaction between coll...

We shall introduce a vector operation, called the �dot product� or �scalar product� that takes any two vectors and generates a scalar quantity (a number). We shall see that the physical concept of work can be mathematically described by the dot product between the force and the displacement vectors.

So far we have analyzed the motion of point-like bodies under the action of forces using Newton�s Laws of Motion. We shall now introduce the Principle of Conservation of Energy to study the changes in energy of a system between an initial state and final state. In particular we shall introduce the concept of potential energy to describe the effect of conservative internal forces acting on the constituent components of a system.

We then describe how to couple the photon to fermions and to bosons.
